2010 Chevy Tahoe 5.3L - P0325 - No Power

Customer Question

2010 Chevy Tahoe 5.3L - No Power - P0325 - Replaced both knock sensors and pigtail connectors - cleared code but comes right back - cats have been checked - fuel pressure is within spec - not sure where to go now - possible knock sensor module in ecm?

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If there is an actual knock in the engine itself this can cause this code here in return the computer will try and compensate the engine timing and can cause the issue here.If this has not been checked this should be done to see if there is an actual engine knock.If there is not let me know and we will continue.Thanks Pete
